Depending on the weight of garage doors, technicians install either torsion springs or extension springs. They basically balance the weight of the door; otherwise, it would be too heavy to be lifted. Therefore, when springs break or get damaged in any way, you should replace them. Garage door spring replacement must be performed by trained experts to avoid risking your life, should they snap.

Depending on how heavy the door is, technicians would install one or more torsion springs. On the other hand, extension springs are more appropriate for lighter garage doors and placed on the two sides of the door. This way, they can keep equilibrium of the door as it is lifted. In any case, springs are wound under a lot of tension in order to accomplish their mission and, hence, any attempt to fix them on your own could result to injuries.
